Mike Tyson has taken to social media to share an intense training video in which he tells the world, "I'm back".
The 53-year-old erstwhile world champion showed off his physique, speed and power as he trained with Muay Thai coach Rafael Cordeiro in the short clip.
Watch the "comeback" video below:Tyson hasn't been in the boking ring professionally for 15 years now, but he's been increasing his training recently, and posting it to social media, sparking speculation regarding a potential comeback.
This 25-second clip, however, seems to hint that a comeback is imminent, as the boxing legend can be heard announcing "I'm back".
The post also appeared to be a promotion for Smart Cups. "Anything is possible when you are smart about it. Train Smart. Recover Smarter. @smartcups," before adding the hashtags: "#baddestmanontheplanet #stillthebaddestmanontheplanet," he captioned the post.

And fans were certainly here for it. "Mike look like he can win another title," 50 Cent wrote, while Ryan Garcia corroborated, ''I got scared when you said I'm back".
American TV host, Steve Harvey, added: "Man oh man Lawd ham mercy!!!! This was the last great heavyweight CHAMP!!!!!
One MO Time!!! [sic]"
Tyson's new trainer, Rafael Cordeiro, recently spoke with talkSPORT, revealing that his client purportedly has the speed and power of a 21-year-old.
"As soon as we started training I said 'My Lord'. I didn't know what to expect from a guy who hasn't hit mitts for - I think - almost ten years," he said. "So I didn't expect to see what I saw - I saw a guy with the same speed, the same power as a guy who is 21, 22-years-old."
"And I can tell; you would have to be a good guy to spar with Mike, because if you don't prepare, he is going to drop you for sure - 100%. The power is different level. I have trained a lot of heavyweights in my career, with not a lot of respect for everybody, but he is almost as powerful as Wanderlei Silva is right now. When you talk about power, I held his right hook and thought 'he is going to kill somebody'."
